Tingle receives Collingwood Prize

Jeb S. Tingle, a civil engineer in the GSL Airfields and Pavements Branch, was recently awarded the 2002 Collingwood Prize by the American Society of Civil Engineers (ASCE).

The Collingwood Prize was instituted and endowed in 1894 by Francis Collingwood, a past secretary of ASCE. It is awarded to members of the Society who are 35 years of age or younger who have authored a paper describing an engineering work with which the author has been directly connected; recording investigations toward an engineering knowledge in which the author has contributed an essential part; and containing a rational digest of results.

Tingle's winning paper, "Engineering Properties of Sand-Fiber Mixtures for Road Construction," focused on his research in synthetic fibers for road construction. Tingle's laboratory research isolated the effect of fiber type, length, denier, sand type, additive quantity, silt content, and moisture content on the reinforcement of fiber-reinforced sands. He also studied the interaction between the discrete fibers and grains of soil. This knowledge of material behavior, coupled with recommendations for sand-fiber mixture designs and road construction applications, assists the practicing engineer in implementing new soil reinforcement technology for construction.

Tingle's research areas of expertise include soil stabilization and geosynthetics for pavement applications. He is the principal investigator for the C-17 aircraft flight tests on unsurfaced airfields; the computer-aided earthmoving demonstration for the ERDC Joint Rapid Airfield Construction initiative; and the development of geogrid design criteria for flexible pavements.

He earned his bachelor's and master's degrees in civil engineering from Mississippi State University in 1995 and 1999, respectively. He recently completed course requirements for his doctorate in civil engineering from the University of Illinois at Urbana-Champaign.

Tingle is a registered engineer intern in the state of Mississippi; out-going president of the Vicksburg branch of ASCE; and is a member of the Institute of Transportation Engineers and the Society of American Military Engineers.
